The power supply on lcd and other flat screen type monitors utilize a group of capacitors as a static pulse for the screen to energize..my bet is that one or more of those have failed...it's actually a common problem with flat screens. Most of them, those that won't power up anyways, have this exact same problem. If it's not that, then your power supply is burnt out, and if that's the case it may be cheaper to get a new monitor instead of trying to fix the old one.

they can be repaired by an electronic tech but are cheaper buying a new one. The cost of new inverters range from 30-80$ USD. Viewsonics don't cost that much and now you can get 18.5 inch widw screen acer or other brand lcds for 89$.

Getting another power supply will be costly exercise mate may be easier to get quote from a local tech if it is just caps that have vented and then weigh up the price difference as LCDs are quite cheap now.

There are two places to look for the problems, the backlight inverter board and the power supply. Look at the power supply first since it is easier to get to, look for burnt parts, bad capacitors, etc.http://en.wikipedia.org/wiki/Capacitor_plaguePlease post back what you find.

sounds like a burnt or a cold solder around the TRANSFORMER section of the power supply , I suggets if your handy w/ tools to open the monitor and inspect the PC BOARD for any burnt or cold solder THAT not making the connection , hope it helps AJ
